One day many years ago I had too many drinks and being stupid and naive and I bought adobe cs5. I still use it on the same computer I installed it a decade ago. Activated and installed only once. Today they revoked the access to it. Clicking the link they say "revoked because purchased from an untrustworthy reseller"
Yeah... untrustworthy reseller, look at the invoice and see who sold&shipped that physical copy...
Contacted support, they said that they won't do anything about it because it's EOL.
Moral of the story: don't do like me. If buying isn’t owning, piracy isn’t stealing. Never give your money to Adobe.
They don't care if it's legal or not. A company of that size can afford to spend money on lawyers that waste the legal system's time until the case gets forgotten. And even if they fail to delay the case to infinity, they'll be fined 0.5% of their yearly profit. It's as they say "the cost of doing business"
